Comparison of Geometrical Accuracy of a Component Manufactured Using Additive and Conventional Methods

摘要

This chapter describes three different methods of manufacturing a vacuum cleaner connector made of ABS and NECURON plastic material. Basically, the part is produced on an injection molding machine; however, with the help of manual laser scanner analysis, it is possible to compare two other methods: part manufactured by milling is 0.04 mm and part manufactured by injection molding machine is -0.15 mm and 3D-printed part is -0.20 mm. All the above-mentioned methods of producing the connector have their advantages and disadvantages. The fabrication time of all elements (under 1 min for injection molding machine, 1.5 h for milling machine and ca. 7 h for 3D printing) and costs of machines and tooling are decisive factors for manufacturing technique selection.
